I know the room is odd but this is the space I have. I spent a lot of time listening yesterday. I also hooked up my Clearwave audio standmount speakers. They use a 1" accuton ceramic tweeter and are one of the best imaging speakers I've heard. They performed a bit better with filling the image more to the center, but still had some of the same issue, which leads me to believe its the room. I also pulled the nenuphars out more into the room. I haven't measured but looks to be about 24" from the wall to the rear of the speaker. That has helped with image depth and the speakers "uncoupling" from the sound. The image is still towards the left but that also might just be how it is in the room. I'll continue to play with some positioning today.

Hi @abd1 ,

The problem in your room is the glass windows and door on the left, which cause very strong first reflections and ruin the soundstage and image.

You should try draping the windows on the left. It doesn’t have to be heavy curtains. Perhaps even a light tulle will suffice.

Regards,

Alex.

 

I'm thinking about getting some GIK floorstanding panels to place at the reflection points along the wall with windows. Also last night I toed in the speakers heavily so they cross before the MLP. Made a big difference. Sound is very centered now and separated from the speakers, still very deep. Soundstage is smaller, but my speakers are about 8' apart so still pretty good. I'm guessing toeing in totally changed first reflection point.

V2 drivers for my Nenuphars Monitors (coupled with a Sub 12) arrived 10 days ago.  Run them 24/7 for a week, then started listening seriously.  V2 is a more refined version of the original F10neo drivers: it does not lose anything (the mid-range magic is fully there), sound is thicker across the entire spectrum (more presence / more meat around all bones) which increases the sense of naturalness & flow. I did not have to tweak my system in any way (MU1-Tambaqui-Icon4se-Amp23r or SIT3, LessLoss cabling), the V2s are here to stay! 

Vinpic  Thanks for your impressions of the V2 drivers. You didn’t mention soundstage or imaging which I assume meant no change but just wanted to check.
